Universal J-Box for
Silicon Wafer Modules
B O X E S
Featuring SMD diode technology, the Y-Sol®
Approved by
Universal J-Box shows approx. 40% less
heat development compared to J-Boxes with
conventional radial diodes. Automated assembly
in an assembly line is possible, either by spring or
soldering connection. It is one of the flatest Silicon
Wafer J-Boxes on the market (<27mm height)
and features integrated cable holders.

TF J-Box for Thin Film Modules
The Y-Sol® Thin Film J-Box can be easily assembled
either manually or in an automatic assembly process.
J U N C T I O N
Contacting to the PV Module is realised by
Approved by
spring loaded contacts in the J-Box lid.
One bypass diode can be integrated optionally

as per customer requirements.
It is one of the flatest Thin Film J-Boxes on the market (<13mm height).
Customer Advantages for J-Boxes
 Time-saving assembly and automated contacting due to spring contacts.
 Material cost savings because resin filling of the J-Box is not required
due to the sealing material in the J-Box lid.
 Space-saving installation due to one of the flatest designs
on the market today.
 Configuration according to customer requirements and delivered as complete
pre-assembled system with cables and connectors
